Recently found one of these crawling under the mattress of my pull out couch during an inspection. Entomologist has confirmed what is called a Thrip. Springtail. They do not usually bite humans but please read this site and comments are appreciated.

That is interesting. I'm pretty sure we still have bed bugs since I've seen two small nymphs alive and another dead from the laundry, but I have wondered occasionally about the cause of our bites. I have had a few "bites" that seem to really hurt. (Similar to that described in the article) I quickly look at the area but I never see a bug crawling away or anything. It could be nymphs and I mistake them for a mole, but I had never heard of bed bug bites really hurting. I also wonder if some of those sharp "bites" I have occasionally felt aren't part of the psychological damage these little guys have caused. Thanks for the heads up on other causes though.

mrbill0626,
Yes that is my point. We need to be aware of other possibilities as well. We are seeing all kinds of things happening which seem to be happening all at once. MRSA, BBs, Mites, Biting Midges. Do roaches Bite? Professionals have been predicting for a while now that we will see pesticide resistance and antibiotic resistance. Well, here we go.

currentinsomniac,
I think that I remember reading that if you disturb a bb at a certain point when it is biting you may feel the bite. I think that this had happened to me.
